=1 Claim.

This invention relates to new and useful improvements in cable anchorsespecially adapted for use in anchoring the stationary end of electriccables such as are used in conjunction with electrically operatedtraveling cranes and other machinery. .The stationary or anchored end ofcables employed in conjunction with such machinery is usually located inthe center of the transverse track and there the cable is subjected to aterrific strain and bending motion. Each time the crane travels overdead-center, the cable is flexed 180 and after this operation isrepeated many times, the cable wears and causes electrical disruptionand consequential shut down delays while repairs are being made.

It is, therefore, the object of the present invention to provide ananchor which eliminates most of this wear as the angle of bendismaterially reduced and a considerable amount of the strain compensatedfor by the special construction of the cable anchor box Other objectsand advantages of the invention will become apparent to the reader ofthe following description.

In the drawings:

Figure 1 is a side elevational viewof a crane showing the improved cableanchor in side elevation and the pit which it is located in section.

Figure 2 is a sectional view taken substantially on the line 2-2 ofFigure 5.

Figure 3 is a section on the line 3-3 of Figure 5.

Figure 4 is a fragmentary rear elevational view of the anchor.

Figure 5 is a side chor.

Figure 6 is a section on the line 6-6 of Figure 3.

Referring to the drawings wherein like numerals designate like parts, itcan be seen in Figure 1, that numeral 5 denotes a trackway upon which acrane 6 or like vehicle travels. on this crane 8 is an automatic wind-upreel 1 for anelectric cable 8, while numeral 9 generally refers to theimproved anchor for the cable 8.

The anchor 9 is situated in a pit l0 located between the rails. of thetrack 5. The anchor 9 comprises a triangular-shaped box ll having frontand rear walls. Depending from the back wall of the box II is a tailportion l2 on which is located a bracket l3, this bracket I! having aelevational view of the anpivot pin l4 disposed through the upperportion thereof and through a barrel l5.

Numeral I6 denotes a clamp rising from the barrel l5 and having a curvedlower portion, this clamp being split longitudinally to define twosections a, a which are flanged and bolted together as at l1 about thecable 8 and this is the fixation point of the clamp assembly. The cable8 axially extends from an electric outlet box l8 secured to the frontwall of the triangular-shaped box H, to the clamp l6 and fromthe clampl6 upwardly through the box and through an opening in the intermediateportion of a slide plate l9 which covers the box and slides in aslideway 20, thus protecting the cable and the interior of the box llagainst weather conditions.

As can be seen in Figure 3, the side walls of the box II are curved sothat when the crane 6 is distantly removed from the anchor 9, the cablewill describe but a slight bend as depicted in broken lines.

The box II has apertured lugs 2| to receive securing elements forsecuring the box in a desired position in the pit l0.

While the foregoing specification sets forth the invention in specificterms, it is to be understood that numerous changes in the shape, sizeand materials may be resorted to without departing from the spirit andscope of the invention as claimed hereinafter.

Having described the invention, what is claimed as new is:

An anchor for a cable comprising a funnelshaped box-like structurehaving flat front and rear walls, the rear wall embodyi a dependingcentral tail-like extension, means for attaching a cable to the lowerend of the extension to extend upwardly out of the structure, andcomprising a tubular upright clamp pivotally mounted at its lower end onsaid extension for swinging between said walls parallel therewith tocompensate for swinging movement of the cable between said walls, saidstructure having upwardly flaring edge walls to obviate sharp bends inthe cable between said walls, and a cover for said structure throughwhich said cable slidably extends, said cover being slidably mounted onsaid walls for compensating movement with said cable.
